Analysis and Modelling of Drainage Networks with SWWM

The first edition of the SWWM Program was launched over forty years ago (1969-71) also by the U.S. Environmental Protection Agency (EPA).

Use of this program has been really widespread but in its first version it was not over-friendly, for which reason, and in spite of having the most reliable and powerful calculation model, it lost ground to other more friendly packages such as the Danish Institute's MOUSE.

Nevertheless, amazed at the success of the EPANET program, in February 2002 a program for relaunching the SWWM (Version 5) was designed, whose results are now visible. The Beta version of the program (also free) has now been launched and the issue of the final version is now imminent.

The possibilities offered by this new version of the SWWM in drainage networks are similar to those of the EPANET module, as it shares all the philosophy and even its symbol system. As a prior condition to taking this course it is more than useful to have done the course on Urban Drainage Networks, since -as can be inferred from its subject matter- this course has most of its time devoted to working out real practical cases and deals collaterally with the matters tackled on the aforementioned module.
